“Realistically, I don’t see major changes coming,” said Ainge, well aware that market factors and the Rubik’s Cube difficulties of finding a transaction that meets the needs of two teams at the same time conspire against blockbuster trades.

“Of course we’re trying to get better, and any deal that was available that could help us, you obviously do that. But we’re not just trying to make any deal. We’re not selling the team off or anything like that. We’re trying to win with what we have right now. That’s got to be our first objective.”

Ainge has denied there would be a trade before then turned around and made a move, so take his comments with a few grains of salt.

But it doesn’t sound like the Celtics are going to make a deadline move out of frustration or desperation, no moves just to make a move and shake things up. Nor should they, this is a roster has shown in stretches it can be good — they made a commitment last summer to see if this roster could make one more run. Expect them to see it through, at least until the summer.

I don’t remember playing tonight. I didn’t play. Guys get a lot of money to be ready to play. No Knute Rockne speeches. It’s your job. If you’re a plumber and you don’t do your job, you don’t get any work. I don’t think a plumber needs a pep talk. If a doctor botches operations, he’s not a doctor anymore. If you’re a basketball player, you come ready. It’s called maturity. It’s your job.

Like it or not, motivation is part of an NBA coach’s job.

But that’s also precisely what Popovich is doing.

His credentials dwarf any other coach’s. He can play to his own ego and absolve himself of responsibility – and players will seek to please him. His years of success have earned him the ability to motivate this way, a method no other coach could use without alienating his team.

So, why not hold Motiejunas to what became a four-year, $31 million offer sheet once matched? Houston got something in return – a later trigger date on guaranteeing Motiejunas’ 2017-18 salary. Originally, that decision had to be made March 1 – which would’ve meant dropping Motiejunas from the team this season to prevent his salary from counting next season. Now, the Rockets can make that call in July, after this season is complete.

The following two Julys, Houston will also have a choice on guaranteeing Motiejunas’ upcoming salary or dropping him.

Essentially, Motiejunas is signing the most lucrative Hinkie Special in NBA history. If he plays well and stays healthy, the Rockets have Motiejunas at an affordable rate. If he struggles or his back injuries flare up, they can drop him with little to no penalty.

After they backed themselves into this corner, Motiejunas and his agent, B.J. Armstrong, didn’t do so bad. Considering the similarity between this contract and the Nets’ original offer sheet, it seems Houston helped Armstrong save face after a bungled free agency (which is easier to accept when you’re adding a talented reserve to a formidable team).

But for how little is guaranteed and how much control the Rockets hold over the next four years, wouldn’t Motiejunas have been better off accepting the $4,433,683 qualifying offer?

This means Motiejunas can’t sign with the Nets, who signed him to the original offer sheet, for one year.

I bet it also means Motiejunas and Houston have agreed to a new contract. Otherwise, why release him from the offer sheet? The Rockets would be giving up a tremendous amount of leverage out of the goodness of their hearts – unless this is just a prelude to a new deal with Houston.
